python 3.x - Inside and outside function

Question

This code is letting me input a string, and that string is added to the dict 'd'. However I want to use this functionality in a gui but when used with the gui I am missing something. Because it won′t work.

This first code works as intended (being outside a function)(Print statements are there just for the testing purpose.):

d = {"username": "XYZ", "email": "xyz@gmail.com", "location":"Mumbai"}

r=str(input())
d[r] =' '

print(r)
print(d)

While this code below does not work as intended. When I run the code it just idles. Why? How do I fix this global/local issue (just my guess)?

def newSite():
    print('opening dialogue')
    r = str(input())
    
    d[r] =' '
    

The function is called in a button.

Button(root, height=1, width=10, text=" <- Input site!  ", command=newSite).grid(row=6, column=3, sticky=W, pady=10)

Answer 1

It is not a good idea to call console input() in a GUI application, use simpledialog.askstring() instead:

from tkinter import simpledialog
...

def newSite():
    print("opening dialogue")
    r = simpledialog.askstring("Input", "Enter Site")
    if r and r.strip():
        d[r.strip()] = " "
    print(d)

...
